Answer 1

Right option is (c) Paraffin, naphthenes and aromatic compound

The explanation is: Saturated paraffinic hydrocarbons are formed from methane to solid waxes. On distillation of this oil, it leaves a residue of solid paraffin wax. Small amounts of naphthenes and aromatic compounds are generated.
